Academic Qualifications:
Thesis and Guide details:
Details of CSIR Fellowship/ Associateship held, if any or from other sources/ agencies.
Significant foreign assignments:
(a) Significant contributions to science and/ or technology development by the nominee based on the work done in India during most part of last 5 years:
In 2012, He synthesized Multifunctional Ferromagnetic Carbon-Nanotube Arrays Prepared by Pulse- Injection Chemical Vapor Deposition. He could grow highly ferromagnetic three-dimensional freestanding pillar architecture of MWCNTs encapsulating iron compounds. The magnetic manipulations of mechanical motions of MWCNTs and their biological compatibility resulted in higher delivery efficiency, a prolonged release of cancer drug doxorubicin (Dox), and good targeting capabilities of Dox onto HeLa cells. This work entitled, “Multifunctional Ferromagnetic Carbon-Nanotube Arrays Prepared by Pulse-Injection Chemical Vapor Deposition,” was published in Angew. Chem., 124: 2970–2973, 2014 ( doi:10.1002/ange.201106566) Impact factor 11.26. Dr. Vinay Gupta has made significant contributions in the area of organic photovoltaic (OPV) devices science and technology. A major issue with the BHJ solar cells was the absorbing capability of conjugated polymers in solar cells that limits the efficiency of a solar cell. In 2012, He showed that by mixing polymers with different absorbing range, the efficiency of solar cells can be increased significantly (Indian Patent no. 0137NF2013, WO 2014033755 A1, UK). Later, he discovered that polymer-polymer Förster resonance energy transfer (FRET) is mainly responsible for the boost in efficiency. He achieved a FRET induced power conversion efficiency of 8.9%, which was highest in India to that date. This work entitled, “Polymer-Polymer Förster resonance energy transfer significantly boosts the power conversion efficiency of bulk-heterojunction solar cells,” is published in Advanced Materials (27, 4398–4404, 2015) Impact factor 17.49. This work was highlighted in Nature Asia (NPG Asia Materials doi:10.1038/asiamat.2011.121) and Nature India (NPG Nature India doi:10.1038/nindia.2011.104). In 2016, he developed a technique to improve the stability of solar cells using a special ZnO coating that can convert UV into visible light which not only protect the solar cells from UV radiations but also harness that energy (Organic Electronics 38 (2016) 193-199). This Technology is currently in process for commercialization. Another most significant issue in BHJ solar cells was the use of conjugated polymers as donors. Conjugated polymers have batch to batch variations that make them unsuitable for the commercial solar cell. Dr. Vinay worked on the development of new solution processed small molecules. . His most recent contribution is, “NIR absorbing D–p–A–p–D structured diketopyrrolopyrrole–dithiafulvalene based small molecule for solution processed organic solar cells,” which is published in Chemical communications (Chem. Commun. 52, 210—213, 2016) Impact factor 6.83. He has recently developed a method of spray coating of perovskite materials over large area which gives over 15% efficiency at 10X10 cm2 cell area in which Cu wires+ITO composite is used as the TCO. This can lead to commercialization of perovskite solar cells. The paper is under review. He has also developed the technology of graphene spray for conductive coating. The work is under progress. Recently some multinational companies including “Power on demand (POD) Technology PVT LTD,” have shown interest in these technologies and negotiations are underway for technology transfer and MOU. He is the one of the rare scientist to bring a multinational company like POD to have tie-up with NPL and will formalize it soon (Letter of interest attached as annexure-12e).
(b) Impact of the contributions in the field concerned:
His contribution to the energy research was so impactful that he was awarded, “Research Excellence India Citation awards 2015.” To describe it, every three years, Thomson Reuters draws up a list of 10 eminent Indian researchers who demonstrate the strongest performance in their research areas by way of highly cited papers and total citations to those papers. The top 10 were awarded in 2015 based on papers published between 2010 to 2014 and indexed in the Thomson Reuters Web of Science. In the top ten Indian scientists, Dr. Vinay is ranked No. 1 in India. Further in 2016, he was awarded, “Science and Technology Excellence award 2016,” in the area of energy sciences by POD multinational company working in the area of solar energy. His average citation/paper is over 50, h-index of 33 and total citations are over 3000 in the last five years based on google scholar. That speaks volumes of his impact in India as well as internationally. His pioneering work on the polymer-polymer Förster resonance energy transfer (FRET) is published in Advanced Materials (27, 4398–4404, 2015). He has been granted Indian Patent no. 0137NF2013, WO 2014033755 A1, UK, on this work. This work was also highlighted in Nature Asia ((NPG Asia Materials doi:10.1038/asiamat.2011.121.) and Nature India (NPG Nature India doi:10.1038/nindia.2011.104). He is one of the few scientists in CSIR who has got attention from industry and currently negotiations are underway for an MOU with Multinational company, “Power on demand (POD) Technology PVT LTD,” for the development of graphene based ink and FRET technology. He is also offered the post of consultant for the company (Letter attached as annexure-12e).
